PFND3DDDI_UPDATEPALETTE callback function

-description

The UpdatePalette function updates a texture palette.

-parameters

-param hDevice [in]

A handle to the display device (graphics context).

-param unnamedParam2

pData [in]

A pointer to a D3DDDIARG_UPDATEPALETTE structure that describes parameters for the palette-update operation.

-param unnamedParam3

pPaletteData [in]

An array of PALETTEENTRY structures to update. For more information about PALETTEENTRY, see the Microsoft Windows SDK documentation.

-returns

UpdatePalette returns S_OK or an appropriate error result if the texture palette is not successfully updated.

-remarks

The palette data in the array that is specified by pPaletteData consists of one UINT value for each palette entry (PALETTEENTRY structure). The palette entry is in ARGB format, with 8 bits for each of the four channels.

The user-mode display driver uses the following members of the D3DDDIARG_UPDATEPALETTE structure that is pointed to by pData to update the texture palette:

  • The PaletteHandle member specifies the handle to the palette that is associated with the surface.
  • The StartIndex member specifies the index of the entry in the array at pPaletteData where the update should start.
  • The NumEntries member specifies the number of entries in the array at pPaletteData to update.
